Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
A biblioteca em versus de Rui Pires Cabral / The Rui Pires Cabral’s Biblioteca in Versus
No full textResumo: Neste artigo, apresento análises rítmico-formais de três poemas-colagens de autoria do poeta português contemporâneo Rui Pires Cabral, integrantes do livro Biblioteca de rapazes, publicado no ano de 2012. Neles, o desenvolvimento de seus respectivos temas é acompanhado de imagens que remetem, aos leitores, uma espécie de figuração dos campos semânticos então montados poeticamente, o que propicia dinamismo à linguagem verbal registrada em tais textos e às próprias conceituações dos termos teóricos “verso”, “estrofe” e “ritmo”, as quais, como se sabe, são fundamentais em matéria de poesia. O objetivo teórico-crítico deste texto é o de refletir sobre esse tipo de poemas junto da elaboração do entendimento conceitual dos termos poéticos mencionados, que são problematizados nos discursos literários dos dessa poesia-colagem, composta por meio do uso de imagens que, como dito, substanciam as dimensões temáticas desse tipo de enunciado artístico.Palavras-Chave: poema-colagem; poesia portuguesa contemporânea; Rui Pires Cabral; verso livre.Abstract: The purpose of this research is to introduce a rhytmic-formal analyze of three collage-poems written by Rui Pires Cabral, on his book Biblioteca de rapazes, published on 2012. In this edition, the themes are developted with images that refers a figuration of semantic fields then poetically builded. This kind of choice provides dynamism to the verbal language registred in such texts and to the concept of the theoretical terms, like verso, estrofe and ritmo. We all know that this concepts are fundamental in terms of poetry. Therefore, the theoretical-critical objective of this article is to discuss this type of poems and the elaboration of the conceptual compreehention of the previouslly mentioned poetic terms, problematized in the literary discourses of those collage-poems, composed by the use of images that build the thematic dimensions of this kind of artistic work.Keywords: collage-poems; Portuguese contemporary poetry; Rui Pires Cabral; free verse
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Uma entrevista com Rui Simões
No full textUIDB/04209/2020
UIDP/04209/2020Rui Simões tem uma das mais longas carreiras no cinema documental português. Como ponto de partida para esta entrevista foram escolhidos alguns dos seus filmes documentais, designadamente Ilha da Cova da Moura (2010), Kolá San Jon é Festa di Kau Berdi (2011) e Alto Bairro (2014), com o propósito de revelar a visão antropológica do realizador, assente na busca permanente pela autenticidade e a construção do ‘real’, criando filmes que nos permitem um olhar novo, quer se trate de um individuo, uma comunidade, um lugar, um tempo ou um acontecimento. O cineasta documental tenta relacionar-se e gerar empatia com a realidade do outro, assente no pressuposto de que todo ser humano é dotado de sensibilidades, crenças, tradições culturais, e contextos educacionais e sociopolíticos. Neste sentido, a entrevista questiona até que ponto Rui Simões consegue despojar-se do seu eu enquanto criador do cinema documental. Rui Simões has one of the longest careers in Portuguese documentary cinema. As a starting point to this interview, some of his documentary films were chosen, namely Ilha da Cova da Moura (2010), Kolá San Jon é Festa di Kau Berdi (2011) and Alto Bairro (2014), with the purpose of revealing the anthropological vision of the director, based on a permanent search of authenticity and the construction of the ‘real’, creating films that offer a new look at the other, regardless of them being an individual, a community, a place, a time or an event. The documentary filmmaker tries to relate to and generate empathy with the reality of the other, based on the assumption that every human being is endowed with sensitivities, beliefs, cultural traditions, and educational and sociopolitical contexts. In this sense, the interview asks to what extent Rui Simões manages to divest himself of his self as a creator of documentary cinema.publishersversionpublishe
The pseudochiral Fermi surface of -RuI
No full textIn continuation of research into RuCl and RuBr as potential quantum
spin liquids, a phase with unique magnetic order characterised by long-range
quantum entanglement and fractionalised excitations, the compound RuI has
been recently synthesised. Here, we show RuI is a moderately correlated
metal with two bands crossing the Fermi level, implying the absence of any
quantum spin liquids phase. We find that the Fermi surface as measured or
calculated for a 2D () slice at any lacks
mirror symmetry, i.e. is pseudochiral. We link this phenomenon to the ABC
stacking in the R space group of -RuI, which is achiral
but lacks any mirror or glide symmetries. We further provide a formal framework
for understanding when such a pseudochiral electronic structure may be
observed

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
